Description

Prefabricated Pallet {PREFABRICATED PALLET}

The present invention relates to prefabricated pallets.

In general, a pallet is used in warehouses or factories that handle various cargoes, and is a stand designed to quickly and easily transport large quantities of cargo using transportation methods such as forklifts and at the same time safely load and store them. says

These pallets are usually made by attaching a plurality of legs to a plate-shaped support plate so that various cargoes can be loaded on this support plate. As the fork of a forklift can be inserted into the bottom of the pallet to enable transportation, transportation or unloading costs and time are reduced. It has the effect of reducing.

In the past, pallets were generally made of wood or plastic, but recently, paper pallets made of paper or corrugated cardboard are increasingly being used in industrial sites.

In the case of plastic pallets, the burden of material costs is high, leading to various problems in terms of production cost, and recently, many countries have banned their import into their countries due to environmental issues. On the other hand, in the case of wooden pallets, since they are mostly manufactured by hand, there are disadvantages such as poor productivity, corrosion problems, disposal problems after use, and quarantine treatment due to pests and diseases.

In contrast, paper pallets have the advantage of being lightweight and convenient to use, as well as being cheaper than wood or plastic pallets. In addition, the fact that it can be 100% recycled after use is also a big advantage.

However, the biggest problem with conventional paper pallets is durability and rigidity. In the case of conventional paper pallets, it is difficult to withstand a large load due to the nature of paper, and there is also a problem in that the surfaces where the paper is glued together fall off.

Meanwhile, in some cases, materials such as plastic or plywood are added to the paper pallet to increase durability and rigidity, but in this case, there is a problem in that the plastic or plywood must be removed when recycling later, and when plywood is used, There was also a problem that the problem of pests and diseases could not be completely eliminated.
